I did more tests with a DS4 v1. My conclusion is that this game requires a DS4 to be connected to the PS4. Otherwise it does not detect the G29.
This means that you need two DS4s, one that you connect to the PS4, and another one that you connect with a USB cable to the PC.

Ok,
Thank you so much for the tests you did. I was not crazy then it really does not work.
So in conclusion with the DS4 v2 it works fine; DS4 v1 needs another controller connected to ps4.
At this point do you think that can be resolved through gimx software or not? thanks again for everything

Hello! I've been facing the same shutdown problem in every game I have. My DS4 is V2 and in WRC5, WRC6 require a second DS4 connected to the PS4.
However, in other games, I need to connect the DS4 off to the PC, so there is no connection problem.
I just wanted to leave the feedback and thank you for the great work that we could do to make that adaptation.
